Description
Technical field
The invention belongs to the multistep treatment technical field of water, waste water or sewage, specifically discloses a kind of emulsion processing work
Skill.
Background technology
In machine building industry, the manufacturing procedure such as cutting and grinding of metal, it will substantial amounts of emulsion is used, to ensure
Metalworking procedures are smoothly effectively carried out.Emulsion is a kind of high performance semi-synthetic metal working fluid, mainly including water, organic
Oil, surfactant, rust-inhibiting additive, EP agent, friction improver, antioxidant etc., emulsion use oil emulsion root
According to need be diluted with water add emulsifying agent configuration form.Emulsion, can be in processing in the process such as metal cutting and grinding
Metal cooled down, lubricated, antirust etc., because metal is in mechanical processing process, it will usually high temperature and substantial amounts of gold occur
Category is considered to be worth doing, in most of machining, will all use emulsion.
Emulsion is after multiple Reusability, it may occur that fades to, becomes sour, fails, its performance reduces, and exists for this emulsion
Use the emulsion for needing more to renew after a period of time.And used emulsion can not be utilized again, and due to breast
The organic oil changed in liquid can be dispersed in water, and animals and plants easily absorb；Surfactant in emulsion is also harmful to biology in itself,
The noxious material that also some can be made not soluble in water is dissolved；Natrium nitrosum, nitrous acid are typically contained in antirust agent in emulsion
Sodium is easily converted to carcinogenic inferior ammonium nitrate；Therefore emulsion can not be directly discharged in natural environment, it will to ecosystem
System does great damage.
Usual emulsion is needed to carry out systemic processing after use, and the processing to emulsion at present is mainly broken
Breast, its pH value etc. is adjusted, then the processing method according to organic wastewater, isolates the various composition in emulsion.Due to inciting somebody to action
Its contained substance is separated one by one to be reused, and emulsification liquor treating process is complex at present, and processing cost is higher, place
The material of gained can not be reused directly after reason, can only be used as in making raw material.

Step（6）In be evaporated to the volume of emulsion and reduce to 25%.
Step is found through overtesting（6）In be evaporated to the volume of emulsion and reduce to 25%, in step（7）It is dense after middle layering
There is lamination in emulsion part, dense emulsion is divided into two layers, and upper strata is more frivolous, be detected as water, base in dense emulsion
This is organic solvent.
Comparative example 1
The difference of this comparative example and embodiment 1 is：Step（3）It is middle that acid out is carried out to emulsion using a jar.
Find to use the acid out tank 70 in embodiment 1 to carry out acid out to emulsion through overtesting, acid out process soon may be used
Complete, and acid out effect is good, it is easy to operate.
Comparative example 2
The difference of this comparative example and embodiment 1 is：Step（6）In be evaporated to the volume of emulsion and reduce to 10%.
Step is found through overtesting（6）In be evaporated to the volume of emulsion and reduce to 10%, it is more difficult to realize, be primarily due to
It is divided into organic solvent in the middle part of emulsion；And required cost longer time, the water quality being evaporated are bad during this；Separately
External step（7）Lamination is not present in dense emulsion part after middle layering.
Comparative example 3
The difference of this comparative example and embodiment 1 is：Step（6）In be evaporated to the volume of emulsion and reduce to 30%.
Step is found through overtesting（6）In be evaporated to the volume of emulsion and reduce to 30%, during it is required spend it is shorter
Time, the water quality being evaporated are good；Simultaneously in step（7）After middle layering there is severe delamination phenomenon in dense emulsion part,
That is institute's water content is more, and major part water fails to be recycled.
Above-described is only embodiments of the invention, and the general knowledge such as known concrete technology and characteristic is not made herein in scheme
Excessive description., can be with the premise of the present invention program is not departed from it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these should also be considered as protection scope of the present invention, and these are implemented all without the influence present invention
